Why are reinforcement bars spliced by another bar?


Why are reinforcement bars spliced by another bar?

Abstract: Due to length limitations of the reinforcing bars, and in order to maintain desired continuity of the reinforcement, reinforcement bar that have insufficient required length will be normally spliced by another bar during reinforced concrete construction.See all results for this questionsp.info Can a rebar splice be weldable to a bar?Since weldability is dependent upon chemical composition, bars may conform to these specifications yet not be weldable. If bar splices are to be welded, Material Specification 539 still applies, but the construction details must specify in addition that the bars be of weldable steel. Most of the rebar materials are carbon-manganese bases.See all results for this questionsp.info AN INNOVATIVE FORM OF STEEL-CONCRETE (SC) …reinforcement bars.
